props 20 hp nissan

[stumpjumper3d]

Hope some one can answer a few questions. I`ve just bought a new 20 hp 4 stroke nissan. Wanted to know if props for the 18 fit it looks like everthing I have been able to find out is that they will ? Also i`am kinda a heavy guy and my boat is an older 15 ft fisher with stick steering and was wondering about a 4 blade prop helping getting up on plane better? It has standard prop with 10 pitch on it.

When you say stick steer do you mean a tiller on the motor or a lever mounted to the boat.There seems to be confusion sometimes.Stick steer is a lever mounted to the boat.You shouldn't make a prop selection without knowing your present max rpm and speed.They like to run 4 strokes at the top of their rpm range.Have you tried moving weight forward and trimming the motor in?Try moving forward to max arm reach perhaps sit on a cooler
just to to see if it helps.There are tiller extensions that might get you to the middle seat.Cost a lot less than a prop.A 4 blade can help low end performance usually with some loss of top speed.
You also may be able to improve performance by raising the motor vertically.

My stick steering is from front of boat. I have no way to check rpms. Just thought about haveing a spare prop and thought about the 4 blade prop.
